[Logical Link Control and Adaptation Protocol (L2CAP)]

L2CAP Event IDs.

Enumerator:

BLE_L2CAP_EVT_RX

L2CAP packet received.

Definition at line 68 of file ble_l2cap.h.

Register a CID with L2CAP.

This registers a higher protocol layer with the L2CAP multiplexer, and is requried prior to all operations on the CID.

Parameters:

[in]

cid

L2CAP CID.

Returns:

NRF_SUCCESS Successfully registered a CID with the L2CAP layer.

NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied, CID must be above BLE_L2CAP_CID_DYN_BASE.

BLE_ERROR_L2CAP_CID_IN_USE L2CAP CID already in use.

NRF_ERROR_NO_MEM Not enough memory to complete operation.

Transmit an L2CAP packet.

Note:

It is important to note that a call to this function will consume an application buffer, and will therefore generate a BLE_EVT_TX_COMPLETE event when the packet has been transmitted. Please see the documentation of sd_ble_tx_buffer_count_get for more details.

Parameters:

[in]	conn_handle	Connection Handle.
[in]	p_header	Pointer to a packet header containing length and CID.
[in]	p_data	Pointer to the data to be transmitted.

Returns:

NRF_SUCCESS Successfully queued an L2CAP packet for transmission.

NRF_ERROR_INVALID_ADDR Invalid pointer supplied.

NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied, CIDs must be registered beforehand with sd_ble_l2cap_cid_register.

NRF_ERROR_NOT_FOUND CID not found.

NRF_ERROR_NO_MEM Not enough memory to complete operation.

BLE_ERROR_NO_TX_BUFFERS Not enough application buffers available.

NRF_ERROR_DATA_SIZE Invalid data size(s) supplied, see BLE_L2CAP_MTU_DEF.

Unregister a CID with L2CAP.

This unregisters a previously registerd higher protocol layer with the L2CAP multiplexer.

Parameters:

[in]

cid

L2CAP CID.

Returns:

NRF_SUCCESS Successfully unregistered the CID.

NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied.

NRF_ERROR_NOT_FOUND CID not previously registered.
